SOLID ELASTIC TIRE WITH FASTENING-STRIPS- SPEGIFIGATION forming part ofLetters Patent No. 773,633, dated November 1, 1904.

I Application'filed July 1, 1899. Serial No. 722,525. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY G. F ISKE, a citizen of the United States ofAmerica, and a resident of the city of New'York, county of New York, andState of New York, have invented certain new and useful Improvements inSolid Elastic Tires with Fastening-Strips, of which the following is aspecification.

My invention relates to improvements in IQ elastic tires forvehicle-wheels. (Type K.)

The present invention consists partly in providing an elastic tire withmeans for attaching it to a wheel. The means consists principal] y offabric which is so incorporated with S the elastic material of which thetire is composed as to greatly add to the tensile strength and wearingqualities thereof, and at the same time by parts extending from the tireit provides a means for attaching the same to the wheel in a mannerwhich I believe to be entirely novel and know to be both useful andpracticable, as will appear from the following description and theaccompanying drawings, in which 5 Figure 1 is a transverse sectionalelevation of a tire embodying my invention. Fig. 2 is a side elevationof a part of the rim and tire. Fig. 3 is a portion of the tire separatefrom the rim. 3 In said drawings, A is a wooden felly, which is bypreference used in this type of wheel, the same being provided with andstrengthened by an exterior metal band B.

O D are laterally-detachable metallic flanges.

These flanges have outwardly-flaring edges 0 (Z and inwardly-turnedlower edges E F, which fit against the sides of the felly A. The felly Ais formed with grooves cf, one in each side, for receiving an extensionfrom 4 the tire, as will appear, and there exists a space between theedges E F of the flanges C D where they engage the felly and theparallel extending sides of the flanges, which spaces-both the grooves efare substantially parallel, only the upper or outer portions of theedges of the flanges O D flaring outwardly, as indicated. The flangesare held in position against the felly A by any desired number oftransverse bolts G, and either of the flanges is removable uponwithdrawing 5 its retaining-bolts.

It will be seen that the general form of cross-section of the tire-bodyis trapezoidal, which gives a considerable bearing area of the tire onthe ground and at the same time a large base area for contact with the.felly. This disposition of the elastic material meets the great strainsdue to direct load and other effects involved in uses for which thistire is primarily intended.

The description just given conforms to and is explanatory of what isshown in the drawings, and I have therein illustrated one good form andarrangement of the flanges with respect to the attaching-lugs dependingfrom 5 the tire; but such description is not to be construed as alimitation-of my invention specifically thereto.

The tire H is a solid body of elastic material, such as rubber. This ispreferably mold- 7 ed in a single endless piece, adapted both in sizeand in cross-section to the particular type of wheel to which it is tobe applied, although I know no reason why it should not be made insections and subsequentlyconnected. IVith either form of constructionseveral loops of strong fabric I J K L M are molded into the material.These loops only are shown. as they are deemed su'flicient, but more orfewer may be used, as preferred. The fabric is distributed through thematerial of the tire H with a twofold objectthat is to say, to increaseits structural strength and to secure as firm a hold as possible. All ofthe layers of fabric are looped outwardly and downwardly 8 5 at eachside of the tire to form the depending fastening-strips N O, whichstrips lie against the sides of the felly A and are there clamped andheld by the middle portions of the flanges O D. The lower edges of thefastening-strips 9 may be folded over cords n O, which at the same timecause desirable enlargement of the edges P Q of the said strips and fitinto and are securely held by the side flanges O D in the recesses e f,formed in the sides of the felly A to receive them.

It is important that the base A of the tire H be seated squarely andfirmly upon the periphery of the felly A, and in order to assure thisresult the said base of the tire is constructed of somewhat roundingform, as in- I dicated in Fig. 3, so that when placed upon the tire itscentral portion will first engage and when pressed down the otherportions will be seated, placing them slightly under tension, whichtension should be sufficient to absorb any slack or looseness whichmight otherwise exist.

Notches 9 (indicated in dotted lines in Fig. 2) are out in the edges ofthe fastening-strips in order to permit the tire to be taken off andremoved from the wheel while the bolts Gr are still in position, so thatthe thickening-cords 12 0' would not in such instance be endless, merelyacting to enlarge the edges, and thereby give stronger hold to saidedges in the notches of the fell y, yet permitting ready removal. of thetire from the wheel.

Without limiting myself to the exact details of construction herein setforth, what 1 claim 1s 1. The combination in a wheel, of a tirecomprising a body of elastic material circumferentially substantiallyinexpansible on its base, fabric permanently embodied therein withlayers thereof lining the seat of the tirebody, a tread portionsubstantially parallel with base, said tire-body being of greater widththan thickness, lateral depending flaps composed completely of fabricwith all other portions of said fabric permanently vulcanized with thetire-body, a felly proper, a band encircling said felly and forming aseat for said tire, lateral plates cooperating with said felly and withsaid lateral flaps cooperating to clamp said tire, said lateral platesbearing upon said felly on one edge and extending upwardly and outwardlyforming a contracted opening whereby said tire proper is laterallysecured and a seat portion with tapered sides is afforded for retainingsaid tire-body proper, substantially as and for the purpose described.

2. The combination in a wheel, of a felly proper, an encircling bandpresenting a transversely uniform seat, a tire comprising a solid bodyof elastic material, fabric permanently embodied therein and extendinginwardly on the wheel beyond the elastic portion of the tire-body andforming lateral flaps, wires embodied in the extremities of said. flaps,said fabric constituting loops therefor, and substantially parallellateral flanges cooperating to secure said side flaps and also tosupport said tire-body, said flanges having at one edge a bearing uponthe felly and forming therewith a parallel pocket for clamping saidflap, all substantially as shown and described.

3. In a wheel, a tire portion comprising a substantially solid body ofelastic material, a series of bands of fabric depending therefrom,consisting wholly of fabric, the other portions of which fabric extendcontiguously into the main body portion of elastic material, a layer offabric forming a base portion of said body and normally curved convexlytoward the felly-tread, detachable parallel side flanges engaging thefelly side and offering a broad parallel pocket for the bands,substantially as and for the purpose described.

4:. In a wheel, a tire having a solid elastic body portion, fabriclining the seat of said tire, depending flaps consisting wholly offabric, the contiguous portions of which enter and are integral with thebody portion of said tire, lateral clamping-plates, bolts cooperatingwith said clamping-plates and felly, a felly proper, an encircling band,incisions in said lateral fabric flaps whereby a partial loosening ofsaid lateral flanges permits the removal of the tire, substantially asand for the purpose described.
